Upgrade Nitro Pro Version new

[hotro@banquyenphanmem.com 0]

I am using Nitro pro 12 I want to ask
1) Is it costly to upgrade to the new version
2) If it costs money, will the license be free for the first year at the time I buy it?
3) Usually, how many times does it take to release version
Please help me! 
Thanks your

Hello @hotro@banquyenphanmem.com

You can check the upgrade pricing here: https://www.gonitro.com/support/upgrade Entering the serial number will not charge you anything.

The license can be used perpetually unless you choose to upgrade again in the future. Your old license is deactivated once an upgrade is done.

Historically, new versions are released more or less 1 year. There is no definite date yet for these releases.

Please let me know if you have other questions.
